Patented Mar. 31, 1953 UNITED STATES PATENT ()FFICE 2 Claims.

This invention relates to an improvement of a powder box or such likeand the object of the invention resides in the provision of means forsimple and effective closure, operated by the hand which holds the box.

In the drawings:

Figure 1 is a top plan view of a powder box embodying the features of myinvention.

Figure 2 is a vertical section therethrough taken on the line AA ofFigure 1.

Figure 3 is enlarged detail section, showing the lid of the powder boxabout to be closed.

Figure 4 is an enlarged detail section, showing the powder box in theclosed position.

Figure 5 is a reduced top plan-view of a different shaped powder box.

Referring to the drawing it will be seen that I provide the base of around powder box I, Fig. 2, with a concentric ring 2, said ring beingpart of the base I 01' attached to it by means of screws or such like-onthe back of said base 3, 4, Fig. 1, leaving a gap 5, the greater part ofthe circumference between the wall of said base and the ring. A hinge 6hinges the lid 8 on the portions 3, 4 of the base. Opposite the back orhinge 6 there is provided a recess 1. There also is provided on the lid8 a corresponding hook-shaped extension 9 which engages said recess ofthe ring.

It can be easily seen that by pressing the ring at the points H), II, i.e. normal to the hinge closure axis, a slight deformation of the ringwill occur, resulting in a widening of the gap at the point ofengagement which will allow the hookshaped part of the lid to disengage(dotted line in Fig. 3).

On the other hand, it will be quite apparent that by closing the box,the wedge-shaped part 13 of the lid will tend to increase the gap 5 atthis point, thereby slightly deforming the ring until the hook 9 snapsinto the recess 1 of the ring. There is furthermore provided a lip M tolift the lid after it is disengaged.

The powder-box has not necessarily to be round, as can be seen in Fig.5. In this case the base carries a 'U-shaped frame 2 and it can 4 beeasily seen that by pressing the legs of the U at the points 15-46, thearc will be deformed, thereby increasing the gap 5 and releasing thehook 9.

What I claim is:

1. A closed box, comprising: a circular dishshaped receptacle, acircular lid, means hinging said lid on said receptacle, near aperipheral region thereof, a deformable ring circumscribing saidreceptacle and joined to said receptacle only near said peripheralregion, said ring being otherwise spaced from said receptacle to providean air gap therebetween, said ring having a recessed portion in theinner wall thereof spaced diametrically opposite from said peripheralportion, and said lid having a projection engageable with said recessedportion.

2. A box, comprising: a dish shaped receptacle having one side open, alid for said open side, mean hinging said lid on said receptacle, near aperipheral region thereof, a deformable ring circumscribing saidreceptacle and rigidly joined to said receptacle only near saidperipheral region, said ring being otherwise substantially uniformlyspaced from said receptacle to provide a continuous air gap therebetweenthroughout the major portion of the periphery of said receptacle,interengaging latching means on the inner wall of said ring spacedopposite from said peripheral portion cooperating with means on said lidfor holding the lid in closed position.
